5.According to the monthly income of railway freight series recorded for a certain station and the modeling method of combined model suggested by Pan-dit-Wu, a time series combined model is established in this paper. The forecast of rolling calculation of this model is satisfactory.
6.According to the theory of Bertrand surface, identified the three-dimension geometry of globoidal worm gearing with roller teeth and point engagement by using of Pro/E.
7.Suspending tightly woven mesh shade screens, bamboo shades, or exterior roller blinds outside windows can help insulate your home from the boiling sun.
8.Due to the multi-period tectonic movement and evolution of mechanical mechanism, syndeposition structures occur extensively in Jiyang Sag, the base of the sag subsided alternatively during the fault depression, which resulted in sinking of top bending and complicated block structure accordingly, reconstructed the syndeposition intensively, and produced the special structural landscape in combination with all levels of faults and sedimentary formations within it.
9.In order to correctly identifying the three-dimensional geometry, equations for the calculation of host curvature of discretionary point on the worm tooth surface, according to Bertrand surface ~[1], and present a method for generatrix design to achieve Point Engagement.
